If You have a gas or even a diesel-powered power generator, fire is always a hazard.

First Alert Tundra AF400 can't put out large fires of burning gas or diesel fuel, but if it is stored next to your power generator and/or its fuel, it can be used at the moment notice while fire is still small.

Note: regardless of how quick-to-use and how actually good they are, fire extinguishing aerosol sprays can't fully replace full-size fire extinguishers.
